Kittât was generally written from left to right in horizontal lines. It consisted of 37 glyphs, including 6 vowels, 2 diphthongs, 17 basic consonants and 12 consonant clusters. Consonants were constructed by the combination of a long vertical stroke and various hooks or barbs. The vowels were indicated by diacritics which appeared above the consonant which preceded. When vowels came at the beginning of a word or stood on their own, the diacritics appeared alone. Besides the uniliteral glyphs, there were also biliteral or triliteral signs, representing compound consonants like mw or tsw.[1]
This variant of Sith writing lent itself to both calligraphy and other uses such as printing and stone carving.[1] Some ancient rituals in Sith language, like the Dwomutsiqsa ("Summon Demon") were written in this runic alphabet, and so were ritual inscription on mummy shrouds.[2]
Due to its various ecclesiastical uses (such as incantations and ritual writing), the Kittât might in fact be High Sith,[3] but neither the Book of Sith nor Speak Like a Sith have specified it.
